Profile & Shrink the iOS Framework

Measure size and runtime cost on device.

Why Framework Size Matters

Your Kotlin code ships to iOS as a binary framework. A bloated one slows app launch and eats download size, so trimming it pays off.

Measure the Baseline First

You cannot shrink what you have not measured. Check the built .framework file size so every later change has a number to compare against.

du -h shared.framework/shared
